Helicobacter pylori

«Helicobacter pylori, previously known as Campylobacter pylori, is a Gram-negative, helically-shaped, microaerophilicbacterium usually found in the stomach.[6] Its helical shape (from which the genus name, helicobacter, derives) is thought to have evolved in order to penetrate the mucoid lining of the stomach and thereby establish infection.[7][8] The bacterium was first identified in 1982 by Australian doctors Barry Marshall and Robin Warren, who found that it was present in a person with chronic gastritis and gastric ulcer, conditions not previously believed to have a microbial cause.[9][10][11]H. pylori has also been linked to the development of duodenal ulcers, polyps, i. e. benign growths, in the small intestine, large intestine, and rectum, and malignancies of the stomach's secretory glands (termed stomach adenocarcinoma),[12] of the mucosa-associated lymphoid tissue in the stomach, esophagus, colon, rectum, or tissues around the eye (termed extranodal marginal zone B-cell lymphoma of the cited organ),[13][14][15] and of lymphoid tissue in the stomach (termed diffuse large B-cell lymphoma).[16]
